Coolant leak ?

[Ldub]

It's a slow leak coming from either the water pump or the 'O' ring behind the engine.

If it doesn't, I will assume it is the 'O' ring. It is my understanding that the 'O' ring fix is difficult because the head has to be pulled and gasket replaced.

I'm sorry Bart, but in the intrest of accurate info, I'm gonna have to disagree with your post...

The intake manifold has to be removed to get to that "O" ring, not the heads.
If you follow the upper radiator hose to it's origin under the intake manifold, you MAY be able to get a look at the thermostat housing...If you have a good flashlight, & are part contortionist...
The back side of the t-stat housing is where the O-ring in question resides.

Now if you were talking about replacing the head gaskets, then yeah, they have to come off...

Yes, that is what I meant. Sorry, I used the wrong terminology . The head gaskets is what I meant. Thanks, Dub.

I have found no evidence of leak on top of motor, appears to be behind plasitc fornt motor cover, black plastic with timing marks on it. So with that said, would that eliminate O ring possibility and limit to water pump?

Also, will pressure test determine origin? I am under waranty but want to be sure before I go to dealer and they try to scam me with all it is this adn it isn't covered bull**** I eem to always get read whild there.

Sounds like water pump to me too.

Don't waste you time/money on the pressure test. You've already mentioned that it is a 'weep' type leak and not a steady drip so the pressure test prolly won't show anything (IMHO).

Now for the big question: Is it time for a timing belt change. A lot of the work to replace the water pump is the same as for the timing belt change so it's usually recommended to do both at the same time.

only 45 K but yes I will do all at once as it is reco.
